Pavel Pavlovich Demidov, 2nd Prince of San Donato

Count Pavel Pavlovich Demidov, 2nd Prince of San Donato (Russian: Павел Павлович Демидов; 9 October 1839, Frankfurt am Main – 26 January 1885, Pratolino, Florence) was a Russian industrialist, jurist, philanthropist and nobleman of the Demidov family.

His parents were Aurora Karamzina and her husband Pavel Nikolaievich Demidov.

His first marriage was on 1 June 1867 to Princess Maria Elimovna Meshcherskaya (Saint Petersburg, 28 February 1844 - San Donato (or Vienna, per Ferrand), 8 August 1868). She died two days after giving birth to a son, Elim Pavlovich Demidov, 3rd Prince of San Donato, at Hietzing in the suburbs of Vienna on 6 August 1868. Her loss had a lasting effect on Pavel, who remained inconsolable for a long time, spending a long while in the room in the Villa San Donato where his wife's dresses were kept to try to recover her presence.

In Saint Petersburg on 2 June 1871 he remarried to Princess Elena Petrovna Trubetskaya (Saint Petersburg, 25 September 1853 - Odessa, 28 July 1917), with whom he had six children:

They decided San Donato was too full of memories of his first wife and so moved to Villa Pratolino (now known as Villa Demidoff). They ended up selling San Donato, and it was ceded on 5 November 1881 to Gaston Mestayer (a French business magnate), with the gardens sold separately to Nemesio Papucci and Rosselli Del Turco. A large part of the enormous Demidov collection of artworks housed in 14 rooms at San Donato were thus dispersed in several sales and memorable public auctions, even the works gathered in the "musée napoléonien" created on Elba by his uncle Anatoly Nikolaievich Demidov, 1st Prince of San Donato and the souvenirs that had (mostly) been ceded to Anatole by his father-in-law Jérôme Bonaparte.
